i have a stock head unit and did the, add two wires to the rear of the oem unit to add a subwoofer diy. i have an 02 s2k. i have a jlw6 10" and a punch amp. i used the high output converter to use the rca plugs on the amp. it has been working flawlessly for about 8 months. a couple weeks ago i went to baton rouge for the bama and lsu game and took out my sub. i tried to install it this weekend and when i went to plug in the speaker wires to the sub terminals, the negative was fine but when i plugged in the red a spark occurred. the sub worked, but when i turned the radio off, there was a pop. the kind of pop when an amp is not grounded correctly. i turn the radio back on, but the sub does not work. i unplug the speaker wire and reconnect it and it sparks again and the sub works again. everytime i turn off the radio and try to turn it back on, the sub wont work unless i go back there and reconnect it. any ideas??? any help is appreciated.

 

it was the amp. i switched it out with another one i had and problem solved.
